In the pump industry in which there are many types, such as: multi-stage pump. Multi-stage pump is a lot of simple single-stage pump series, together, is a centrifugal pump, his output pressure can be great. Now we say that some of the multi-stage pump maintenance and maintenance problems. 1. Check the multi-stage pump tubing and junction with or without loosening. Hand rotating multi-stage pump, and proved multistage pump is flexible. 2, was added to the bearing body bearing lubrication oil, observe the oil level should be the subject of the centerline of the oil, lubricating oil should be replaced or supplemented. 3, multi-stage pump for long periods, the need to pump all apart, dry water, the moving parts and the junction coated with grease installed. 4, if found abnormal sound multistage pump should immediately stop checking reasons. 5, multi-stage pump in the first month of work self-balancing multi-stage pump, replacement of oil after 100 hours, after every 500 hours and oil change once. 6, pump in winter season multistage pump 15kw, parking, the need of the lower pump drain plug unscrew the media will put the net. Prevent cracking. Seal ring is made of iron rust, high-pressure water pumps to prevent water leakage back portion, spread a layer of paper in the middle of the pad are fixed on top of the water segment and the middle of wearing parts, wear and tear parts availability more?. Balancing rings made of cast iron, fixed on the water segment, D6-25 * 3 d-type multi-stage pump multistage centrifugal disc which together constitute the level and balance? Means. Balance disc made of wear-resistant iron rust, installed on the shaft, located between the water segment and end cap, balance the axial force. Bushings made of rusty iron, located at the packing room, as fixed impeller shaft and protect the stainless steel multi-stage pump, the wearing parts, pay attention to the motor bearings? L wear after more spare parts available?. Bearings are single row radial ball bearings, the use of calcium-based lubricating grease. Filler acts as a seal to prevent leakage of air entering and plenty of fluids, D6-25 * 3 multi-stage type multistage centrifugal pump d packing by the water segment and end cap packing room multistage pumps, packing gland, packing ring and fillers, etc., packing chamber from the water seal effect D6-25 * 3 d-type multi-stage pump multi-stage centrifugal high-pressure water flows into a small amount. Tightness of the packing must be appropriate, not too tight also not too loose, D6-25 * 3 d-type multi-stage pump multistage centrifugal liquid oozing drop by drop can prevail. If the packing is too tight, the sleeve is easy to heat, while consuming power. Packing too loose, fluid loss due to lower pump efficiency Shiyuan professional production 100d-16X3 horizontal multistage centrifugal pump provided by the Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) is a professional "IS centrifugal pumps, XA centrifugal pump, BA centrifugal, B-type centrifugal pump, double suction centrifugal pump" company.
